It sounds like Yoshi's Woolly World is going to be something really special when it comes to the audio aspect. What we've heard of the game so far is outstanding, and there's a special reason for that. Mr. Takashi Tezuka wanted the game to have a really great feel in the audio department, so much so that he took it upon himself to learn how to play guitar. Once he became competent enough, he went back into the studio and worked on creating a new tune for every stage in the game!
